PUMP-CAP.

SPECIFICATION forming' part of Letters Patent No. 675,210, dated May 28,1901.

Application filed October 23, 1900. Serial No. 34,031. (No model.)

To ir/ZZ whom it may concern:

Be it known that I, AUGUST GUSTAFSON, a citizen of the United States,and a resident of Cherokee, in the county of Cherokee and State of Iowa,have invented a new and Improved Pump-Cap, of which the following is afull, clear, and exact description.

The invention relates io pumps; and its object is to provide a new andimproved pumpcap which is simple and durable in construction andarranged for convenient and secure attachment to a new or old hand-pumpor force-pump.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of Y reference indicate corresponding parts in allthe views.

Figure 1 is a side elevation of the improvement as applied to aforce-pump. Fig. 2 is a sectional side elevation of the same. Fig. 3 isa sectional plan View of the same on Ythe line 3 3 in Fig. l. Fig. 4 isan enlarged side elevation of the guide in the upper ends of Fig. 5 is atransverse section of the same. Fig. 6 is a sectional plan View of theimprovement as arranged for use on an ordinary hand-pump. Fig. 7 isasectional side elevation of the same, and Fig. 8 is an end elevation ofthe rocking link. v

0n the upper end of the pump barrel or cylinder A is fastened asectional clamp B by means of transverse bolts C, and on the sides ofsaid clamp B are held upwardly-extending bolts D for fastening the coverE upon a packing-ring F, held on the top of the pumpbarrel A, as isplainly indicated in Fig. 2.

The cover E is formed at its middle with a gland-box E', into whichextends a gland G, engaged at its head by the under side of a yoke H,engaged by the extreme upper ends of the bolts D, it being understoodthat nuts D', screwing on said bolts D, hold the cover E to its seat onthe packing F, while nuts D2 engage the top of the yoke 'H to press thegland G in iirm contact with the packing G', contained in the gland-boxE', said packing resting on a Washer G2, held in the bottom of thegland-box. The bottom of the gland-box E has a cut-out portion for thepassage of a flat slide-rod in case the same is used instead of theordinary round pump-rod shown in the drawings.

From one side of the sections of the clamp B extend sidewise the lugs J,formed at their inner faces with sets of registering recesses J', ofwhich one set forms at the time a fulcrum for a link K, made in sectionsK' K2, connected with each other at their middle by a bolt K3. (SeeFigs. 1 and 8.) The lower ends of the link-sections K K2 are formed witho-utwardlyextending trunnions K4 K5 for engagement with a set ofrecesses J 'J and on the upper ends of said link-sections are formedinwardly-extending trunnions K K7 for forming the fulcrum for the leverL. The latter is connected in the usual manner with the pump-rod N orthe slide-bar previously mentioned. The clamp B is further provided withupwardly-extending standards O, preferably two standards for eachclamp-section, the standards of a clamp-section being rigidly connectedwith each other at their upper ends by a connecting-piece O', containinga guide P, preferably made of wood, and through which extends thepump-rod N. Bolts O2 connect the standards O with each other, and theconnect-ing-pieces are preferably pro vided with inwardly-extendinghooks O3 for engaging the guide P, and thereby securely holding thelatter in position. (See Fig. 5.).

By the arrangement described the sectional clamp B can be readilysecured in position on the upper end of the pump cylinder or barrel A,the lower end of the clamp resting on an external flange A' of saidbarrel.

By the use of the coverE the upper end of the barrel is securely closed,and leakage is prevented along the pump-rod N by the gland G and packingG', the gland being'held in position by the adjustable yoke H.

When the device is used on an ordinary hand-pump, I prefer theconstruction shown in Figs. 6 and 7, in which the cover E3 is notengaged by bolts, but simply rests on the upper end of the cylinder orbarrel. (Not shown.) The yoke H2 rests on guide-blocks I and is held tothe' clamp (not shown) by bolts D3.

IOO

The slide-rod N in this case is -made rectangular and extends throughcorrespondinglyshaped openings in the cover E3 and yoke H2, it beingunderstood that the blocks I can be shifted between the cover and yokewhen the bolts D3 are loosened to bring the blocks in position forproperly guiding the flat pump-rod.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent l. In a pump, spaced lugs or brackets projectedfrom the pump-barrel and provided with alining recesses, a linkconsisting of two crossed members having at their lower endsfulcrum-pins projecting away from each other into said recesses, and attheir upper ends pins projecting toward each other, and a lever embracedby the upper ends of the link members and engaged by the upper set ofAUGUST GUSTAFSON.
